Abstract (en)
Disclosed in the present invention is a mechanical switch dimming speed regulation control system, comprising a double-contact mechanical switch, a dimming speed regulation controller, and a controlled device. The double-contact mechanical switch at least has one alternating current live wire input end and at least one group of normally closed contact and normally open contact which are short-circuited with each other; output of the normally closed contact and the normally open contact is loop-connected to the dimming speed regulation controller; the dimming speed regulation controller is loop-connected to the controlled device; the dimming speed regulation controller comprises a signal acquirer and a dimming speed regulation control circuit; the signal acquirer is separately electrically connected to an output loop of the double-contact mechanical switch and the dimming speed regulation control circuit; the dimming speed regulation control circuit is loop-connected to the controlled device. The present invention implements high-power dimming speed regulation control of a single live wire by using a double-contact mechanical switch, and overcomes the problems of power limitation of a conventional dimming speed regulation switch and difficulty for an intelligent switch to implement dimming speed regulation of a single live wire.
